BBTO’s four-piece silk sleep eye mask set is designed to cover the eyes and block light during sleep or naps, with contoured masks and adjustable straps.
Light in a bedroom, hotel room or plane cabin can make it harder to settle down for a nap or sleep. BBTO silk sleep eye masks provide a cover for the eyes when you want a darker-feeling rest space, whether you are at home or travelling. The four colors also make it easy to distinguish masks when sharing the set.
The shaped eye cover is designed to fit over the face and eyelids, while inner padding at the nose bridge helps cover the gap where light can enter. This full-coverage design is intended for sleep and naps in different settings, including at home, in a hotel or on a plane. The silk fabric is lightweight and breathable, with moisture-permeable properties for comfortable wear around the eye area.
Yes. The adjustable strap ranges from 15.3 to 21.3 inches (38.9 to 54.1 cm), and its flexible construction may allow the maximum range to extend further. The design is suitable for women, men and children, as well as back, side and stomach sleepers. Adjust the strap to hold the cover in place without relying on a fixed headband size.
Each eye mask is made of silk, a porous fiber with moisture-absorbing and moisture-permeable properties. The lightweight, breathable material is made to feel soft against the eye area. Its purpose is to provide a comfortable light cover for rest; it is not an eye treatment or a substitute for medical care.
These masks suit adults and children who want a reusable eye cover for sleep, naps or travel, including people who sleep on their back, side or stomach. Their contoured coverage, adjustable fit and silk fabric make them a practical choice for blocking light while resting.
